Some sites are really useful. Unnecessaryknowledge.com is not. On this quirky site, you’ll be able to learn about things that you might have otherwise never even heard of. Using the site is really simple. All you have to do is read one of the useless bits of information and rate it (either good or bad). If you find that you have something to say about it, you can leave a comment. Maybe you want to add some extra information to share with all of us, or you want to let everyone in on how much you love the site. Regardless, the site is so simple that it immediately pulls you in. You’ll find yourself reading through hundreds of unnecessary bits of information, wasting time as you do so. I pulled up the site and spent 15 minutes (of which I should’ve been writing this review), learning about where the word denim comes from and other things I shouldn’t have the need to know.
